Description
- The invention concerns vessels for heating water, such as electric kettles and jugs, having means enabling a user to ascertain the level of water in the vessel without having to peer through an opening, such as a spout or lid opening, into the interior of the vessel.
- A water boiling electric jug is at present available, which jug is provided with a form of level indicator which comprises an upstanding transparent tubular member which is located on the outside of the vessel. The tubular member contains a float and has, at its upper and lower ends, passages which lead to the interior of the vessel through the wall of the vessel.
- This form of level indicator can give rise to bacterial contamination of the water, and an object of the present invention is to enable the risk of bacterial contamination to be minimised.
- According to the present invention there is provided a water heating vessel having water level indicating means comprising a fixed member secured to a wall of the vessel to at least partially occupy an elongate opening in said wall; wherein the fixed member comprises an elongate transparent or translucent partition opposite sides of which provide an external face, visible at the exterior of the vessel, and an internal face at least partially exposed to the interior of the vessel; and wherein the fixed member and said wall are constructed and arranged so that thermal effects, caused by heating of water in the vessel, can cause water to move vertically in contact with said internal face when the vessel contains at least a predetermined minimum quantity of water.
- The internal face of the partition may be prismatic or otherwise shaped, textured or coated to provide a distinct visual contrast between wetted and unwetted portions of the internal face.
- The partition may constitute the indicating means, and may be bonded, glued, clamped or otherwise mounted on said wall to occupy and close said elongate opening.
- Alternatively, the partition may constitute an external wall portion of the fixed member, the latter having further wall portions bounding an internal channel in the fixed member. The channel may be wholly open towards the interior of the vessel, or may be connected with the interior by vertically elongate openings at least one of which reaches to below the level reached by said minimum quantity of water, so that water from within the vessel can circulate through the channel during heating.
- The channel may contain a float, and is preferably shaped so as to be self-draining when the vessel is emptied.
- The further wall portions may be integral with the fixed member. However, such forms of fixed member having disadvantages of manufacturing cost, and deterioration of appearance upon being used under certain conditions.
- An object of a preferred form of the invention is to enable these disadvantages to be reduced.
- In a preferred form of the present invention the vessel is characterised in that the fixed member cooperates with a further member of the indicating means to define a channel which is connected with the interior of the vessel and which contains a float.
- The further member is preferably removable from or movable relative to the vessel so as to provide access to the interior face of the partition, so that the interior face may be cleaned.
- The invention will be described further, by way of example, with reference to the accompanying diagrammatic drawings, wherein:-
- FIGURE 1 shows a vessel of the invention in side elevation;
- FIGURES 2 and 3 show partial vertical and transverse enlarged cross-sections of the vessel of the invention incorporating a first embodiment of indicating means;
- FIGURE 4 shows an enlarged exploded vertical cross-sectional view of the indicating means shown in FIGURES 2 and 3;
- FIGURES 5 and 6 show a fixed member of the indicating means in front and side elevation prior to incorporation into the vessel;
- FIGURES 7, 8, 9 and 10-are cross-sectional views, similar to FIGURE 3 of four further embodiments of the indicating means.
- The water heating vessel generally comprises a moulded
plastics vessel body 10, an electric immersion heater andswitch assembly 11, and indicatingmeans 12 secured to awall 13 of thebody 10. The vessel is arranged for heating any quantity of water within a range extending from a minimum quantity, which is determined to provide aminimum water level 14 sufficient cover aheating portion 15 of the immersion heater, to a maximum quantity which is determined to provide amaximum level 16 for safe and satisfactory operation of the vessel. - In the embodiment shown in FIGURES 2 to 6, the indicating
means 12 comprises a transparent, elongate, moulded plastics fixedmember 20, anelongate insert member 18 and a redspherical float 21. The fixedmember 20 is shaped to provide a partition, longitudinally ribbed laterally projectingside flanges 24, and a similar downwardly projectingbottom flange 25. The side flanges 24 project laterally beyond theribs 31 to provide series of vertically spacedlateral projections 32. Thepartition 25 provides anexternal face 26 and a prismaticinternal face 27. Theexternal face 26 is provided with markings to indicate at least the maximum andminimum levels indicator member 20 has inwardly directedwall portions 33 which cooperate with theelongate insert member 18 to define achannel 23. Thechannel 23 is longitudinally open towards the interior of the vessel via amouth 28 having a width less than the width of thefloat 21. - During manufacture, the
body 10 is moulded within the fixedmember 20 in situ in the mould, so thatportions 29 of thewall 13 at least sealingly engage and interlock with theflanges ribs 31 and theprojections 32; so that the body material grips and at least partially adheres t6 the material of the fixed member; and so that themember 20 occupies a vertical elongate opening in thewall 13. - The
member 18 is moulded separately and is inserted into the vessel so that abottom projection 34 engages asocket 35 formed in bottom parts of the fixedmember 20 andbody 10, and so that an upperfloat retaining flange 36 snaps over and engages locatingformations 37 on an upperinterior portions 38 of thewalls 33, whereby releasably to locate themember 18 in position against the fixedmember 20. - In use, water heated within the vessel circulates within the body and the
channel 23 so that all the water in the vessel is heated. If theface 27 becomes contaminated or dirty, themember 18 can be unclipped and removed from the vessel, to permit the face to be cleaned. - The second embodiment of indicator means 20 shown in FIGURE 7 differs from the first embodiment in that the
insert member 18 is omitted and the fixedmember 20 is modified to includerear walls 40 which define themouth 28 to retain thefloat 21. A clip-in retainer (not shown) is provided at the top of the channel to retain the float. - The third, fourth and fifth embodiments shown in FIGURES 8, 9 and 10 differ from the first and second embodiments in that the
fixed members 20 are modified for securing into thevessel 10 after thebody wall 13 has been moulded. - In the third embodiment the
insert member 18 and fixedmember 20 are modified to include snap-fit or interlocking interengagement means 41 on cooperatingwall portions members portions 45 of thewall 13 are embraced between a frontperipheral flange 46 on themember 20 and a rear peripheral flange 47 on themember 18, and to clamp anelastomeric seal 48 between theportions 45 and the flange 47. - The fourth embodiment is partially similar to the second embodiment in that the
fixed member 20 includes therear walls 40, and employs a dip in retainer. However, in this embodiment, thewalls 40 have tapered peripheral surfaces adjacent undercutperipheral shoulder portions 50; themember 20 has a frontperipheral flange 46; and thebody wall 13 has taperedportions 51 whereby to permit the fixedmember 20 to be pressed inwardly or snap-fitted into the opening in thewall 13 until theportions 51 are embraced between theflange 46 andportions 50. A sealinglayer 52 or seal may be provided between thewall 13 and themember 20. - In the fifth embodiment the
fixed member 20 is substantially constituted by thepartition 22, which partition is retained in the opening in thewall 13 by a double channelelastomeric sealing member 53, which extends peripherally around the partition and is flanged to embrace both thewall 13 and the fixed member. - It will be readily appreciated that the fixed member is open substantially along its entire height to the interior of the vessel (except for one or more relatively very short braces, e.g. the
brace 55 which divide themouth 28 into verticallyelongate openings 54, as shown in FIGURE 2) so that water and steam can flow at all levels directly to and from the channel to rapidly sterilise the channel in all embodiments except the fifth, and in the fifth embodiment the rear surface wholly confronts the interior of the vessel. - Furthermore, there are no small passages in the indicator means, thus removing the risk of blockages causing faulty level indicators. In the event of the float is removed, the partition enables the contents of the vessel to be viewed directly to give a clear level indication.
- -The bottom of the
insert member 18 and/or the fixedmember 20 may be sloped downwards and inwards, as indicated by the broken line 56 in FIGURE 2, so that thechannel 28 is self-draining. - The invention is not confined to the precise details of the foregoing examples, and many variations are possible within the scope of the invention as defined by the appended claims. For example, features of any one embodiment may be utilised in one or more of the other embodiments to form modified forms thereof, e.g. the
walls 33 in the third embodiment could be provided with shoulders equivalent to theshoulders 50, so that the fixedmember 20 would remain in place if theinsert member 18 were removed or omitted. In the third to fifth embodiments, the body wall could be of metal spun sheet material in which the elongate opening is pierced and the wall adjacent thereto preferably pressed to cooperate with the indicating means, which is modified in peripheral shape to engage and effect a seal with the thinner metal wall.
